Definitions

  • the present disclosure relates generally to differential assemblies and, more particularly, to a bolt-on configuration of a front wheel drive electronic limited slip differential.
  • EP 1 502 800 A1 there is disclosed a limited slip differential assembly as it is defined in the pre-characterizing portion of claim 1.
  • Differentials are provided on vehicles to permit an outer drive wheel to rotate faster than an inner drive wheel during cornering as both drive wheels continue to receive power from the engine. While differentials are useful in cornering, they can allow vehicles to lose traction, for example, in snow or mud or other slick mediums. If either of the drive wheels loses traction, it will spin at a high rate of speed and the other wheel may not spin at all. To overcome this situation, limited-slip differentials were developed to shift power from the drive wheel that has lost traction and is spinning, to the drive wheel that is not spinning.
  • a driveshaft can drive the differential through the use of a bevel gear that meshes with a ring gear mounted to a housing or case of the differential.
  • the gear arrangement can also include a pair of side gears that are mounted for rotation with the respective output shafts.
  • a series of cross pins or pinion gear shafts are fixedly mounted to the housing for rotation therewith. Pinion gears are individually mounted for rotation on the pinion gear shafts and are each in a meshing relationship with one of the side gears.
  • Some differential gear mechanisms include traction modifying differentials.
  • a clutch pack can be disposed between one of the side gears and an adjacent surface of the differential case.
  • the clutch pack or locking mechanism is operable to limit relative rotation between the gear case and the one side gear.
  • engaging the clutch pack or locking mechanism is achieved by one of several different approaches.
  • Some configurations include a piston that actuates to cause the clutch pack to move between open, locked, and partially locked conditions. In some examples it can be challenging to provide a simple arrangement to deliver hydraulic fluid to the piston without substantial modification of existing hardware.
  • the present invention is a limited slip differential assembly as it is defined in claim 1.
  • the clutch assembly can also have a clutch pack including a first subset of plates fixed for rotation with the sleeve and a second subset of plates fixed for rotation with the clutch basket.
  • the clutch assembly can also include a piston positioned adjacent to a first end of the clutch pack and a fluid delivery system operable to direct fluid against the piston whereby the piston is urged to press the clutch pack against a portion of the clutch basket.
  • the third set of splines and the sixth set of splines of the support shaft can be spaced from one another along the axis.
  • the present invention further is a method of providing limited slip in a differential assembly as it defined in claim 5.
  • the method can also include positioning the first linkage within a first housing and positioning the clutch assembly outside of the first housing.
  • the method can also include positioning the clutch assembly within a second housing and linking the first housing and the second housing through a third housing.
  • the method can also include positioning the first linkage within a housing and projecting less than all of the second linkage into the housing.
  • an exemplary vehicle driveline is shown and generally identified with reference numeral 10.
  • the exemplary vehicle driveline 10 described herein is for a front wheel drive vehicle having a transversely mounted engine 12 (shown only as a partial engine block in FIG. 1 ), although other configurations can be utilized with the present disclosure.
  • the engine 12 can provide a rotary output to a transmission 14.
  • the transmission 14 can provide a rotary output to a differential assembly 16.

  • the exhaust manifold 18 has been omitted from FIGS. 2 - 3 .

  • the limited slip differential assembly 24 can function as a traditional open differential during normal operating conditions through the differential assembly 16.
  • the slip limiting arrangement 26 can be selectively actuated in order to generate the optimum bias ratio for the situation.
  • the differential assembly 16 can include a ring gear (not shown), a first housing 30, a plurality of pinion gears 32, and at least one side gear 34.
  • the first housing 30 can be rotatable about an axis 36.
  • Rotary output from the transmission 14 (referenced in FIG. 1 ) can be transmitted to the ring gear through the vehicle's drive shaft and a bevel gear.
  • the first housing 30, or crank case can be meshed with the ring gear for concurrent rotation.
